Answer:
D
Step-by-step explanation:
We need the formula for arc length (in radians) to solve this problem. The formula is:
Where
s is the arc length
r is the radius of the circle
is the intercepted angle
In this diagram, we can see that is beign intercepted by the big arc with measure 20 cm. So arc length, s, is 20
Also, if we look, we see that the radius is 5 cm, so r = 5
Now, we substitute into formula and find :
This is given in radians, so is 4 radians
D is the correct answer choice.

Answer:
4160 cubic inches
Step-by-step explanation:
The dog carrier is in the shape of a rectangular prism (cuboid).
The volume of a rectangular prism is given as:
V = L * W * H
where L = length, W = width, H = height
The carrier is 20 inches long, 13 inches wide, and 16 inches high.
Therefore, its volume is:
The volume of the dog carrier is 4160 cubic inches.
